Abstract: | Summary Partially purifiedD-aspartate oxidase from beef kidney has been tested in the presence of butanedione or phenylglyoxal, which specifically modify the arginine molecule. The results obtained clearly indicate that arginine residues are involved in the binding of the substrate to the active site of the enzyme. |
